Productivity Analysis of the Distributed QoS Modeling Language

Model-driven engineering (MDE), in general, and Domain-Specific Modeling Languages (DSMLs), in particular, are increasingly used to manage the complexity of developing applications in various domains. Although many DSML benefits are qualitative (e.g., ease of use, familiarity of domain concepts), there is a need to quantitatively demonstrate the benefits of DSMLs (e.g., quantify when DSMLs provide savings in development time) to simplify comparison and evaluation. This chapter describes how we conducted productivity analysis for the Distributed Quality-of-Service (QoS) Modeling Language (DQML). Our analysis shows (1) the significant productivity gain using DQML compared with alternative methods when configuring application entities and (2) the viability of quantitative productivity metrics for DSMLs.
